Have an opinion?
there should be ways!
I know but once you ask a question on here it never goes away
may be I can contact with inventors?
or it is useless?
I don't know if that'll work. Why does it matter so much to you?
You can never delete them. Only disown them.
that means they will be showen anonymously?
It means that you disown them and they stay on here and people can still answer them but you don't get notifications or anything. I would recommend changing them all to anon and then disowning them.
Don't think you can, sorry
